| In order to alleviate the large, urban traffic pressure , state and local governments are seeking to develop underground , moving vehicles, high-speed rail and other rail transportation industry , because subway , moving vehicles, high-speed rail and other vehicles, fire risk is relatively high . Therefore, CSR CNR vehicles and vehicle operators need to reach a certain level of fire materials , such as the subject reaches Germany DIN5510-2 standard in the S3, ST2, SR2 grade or above grade . Many materials manufacturer of the German standard DIN5510 standards are not very understanding, Nanjing Rui Governor companies to provide you with detailed information DIN5510-2 , details, please consult 025-86583475 .
DIN5510 Material fire rating standards will generally classified as S2-S5 class , smoke does not reach the class is divided into SR1, SR1-SR2, droplet class is divided into SR1-SR2. DIN5510 standard for the German Ministry of Railways for the rail vehicle fire protection - Part 2 : Materials and components of the combustion characteristics and combustion concurrent phenomena - Classification, requirements and test methods (DIN5510-2 Preventive fire protection in railway vehicles-Part 2: Fire behaviour and fire side effects of materials and parts-Classification, requirements and test methods).
DIN5510 's S2/S3/S4/S5 level test for testing according to DIN54837 .
DIN5510 S2 class: the extent of damage ≤ 30cm, after the burning time is not required
DIN5510 S3 class: the extent of damage ≤ 25cm, after the burning time ≤ 100S
DIN5510 S4 class: the extent of damage ≤ 20cm, after the burning time ≤ 10S
DIN5510 S5 Level : Damage range = 0cm, after the burning time = 0S
DIN54837 This test also can be the development of smoke ( not reached SR1, SR1-SR2) and droplet test (ST1-ST2).
DIN54837: Testing of materials, small components and component sections for rail vehicles-Determination of burning behaviour using a gas burner.
DIN54837: Materials for railway vehicles , small parts and components of the test , the test using a gas burner combustion characteristics .
DIN5510-2 fire rating test in addition to S-Class , SR smog grade level , ST droplet grade level , there DIN5510-2 toxicity levels.
